Document Summary

The ribot gradient: law of regression, the progressive destruction of the memory descends progressively from the instable to the stable. It begins with the recent recollections which, being but faintly impressed on the nerve elements, seldom repeated and consequently but feebly associated with other recollections. Effects of protein synthesis inhibitors on memory: the protein synthesis inhibitor anisomycin was injected into the gustatory cortex of rats at different points after learning. As a consequence, the patter can be recreated at a later time: neurons that fire together, wire together . Dendritic spines: small membraneous compartments protruding from dendrites that house essential postsynaptic components and receive synaptic contacts from glutamate releasing axons. Long-term potentiation as a cellular model of memory: experimentally induced by high-frequency stimulation of certain types of neutrons in certain brain areas, results in long-lasting strengthening of synaptic connection between neurons.
